䡲 A solid green indicator light means the battery is
fully charged.
With the Sprint-approved Li-Ion battery, you can
recharge the battery before it becomes completely run
down.
Extending Your Battery Life
Active applications, backlight levels, and Bluetooth and
GPS use all contribute to draining your battery. The
following is a list of helpful tips that can help conserve
your battery’s charge:
䢇 Reduce your backlight on time. See “Changing the
Backlight Time Length” on page 40 and “Changing
the Key Backlight Time Length” on page 41.
䢇 Turn Bluetooth off when not in use. See “Turning
Bluetooth On and Off” on page 81.
䢇 Turn Wi-Fi off when not in use. See “Turning Wi-Fi On
and Off” on page 102.
䢇 Turn GPS off when not needed. Most applications
using this function will periodically query the GPS
satellites for your current location; each query drains
your battery. See “Location Settings” on page 42.
䢇 Do not wait until your battery is completely depleted
before charging your device. Repeated complete
discharging and recharging can reduce the storage
capacity of any battery over time.
䢇 Turn off Automatic application sync. See
“Synchronizing Accounts” on page 42.
䢇 Add a Power Control Widget to your Home screen to
deactivate features such as Wi-Fi, Bluetooth, GPS,
and synchronization and to reduce the screen’s
brightness setting. See “Adding an Item” on page 23.
䢇 Check running services and close any unnecessary
applications. See “To view and control currently
running services:” on page 52.
WARNING: Do not remove the battery while it is charging.
Always remove the charger from the wall outlet
first before removing the USB cable from the
device.
